Mount for vibrators

ABSTRACT

A mount for attaching vibrators to containers such as concrete molds and the like is made up of a plurality of walls affording a boxlike structure in which the end walls are divergent so as to receive the matching legs of a secondary element which may be part of or an attachment to the vibrator, together with clamp screws that draw the mating surfaces together to provide a rigid mounting in which the vibrator becomes in effect a part of the container to be vibrated.

" SHEET 2 OF 2 INVENTOR. C. G. MATSO N MUUN'I FOII vtnnmrons BACKGROUND OF THE INVENTION The use of vibrators for settling, moving, etc. of material is well known in the field of materials handling, but there is always the problem of mounting the vibrator on the object to be vibrated. In some instances, where the mounting is relatively permanent, the vibrator itself may be welded in place. But in most instances, several mounts are required so that the vibrator may be moved from one locality to another or several vibrators must be provided. Very often the object to be vibrated lacks adequate strength in the area in which the vibrator is mounted and this area must either be built up to withstand the forces or the vibrator must be provided with a special mounting means, of which various types are known, as

in US. Pat. No. 3,420,480.

SUMMARY OF THE INVENTION The present invention provides a fabricated structure that amounts to a block or boxlike structure of relatively sturdy metal nature that lends itself to rigid attachment to the container etc. to be vibrated, as by welding. At the same time, this structure provides for addition to the strength of the object and also affords bevel or approximately 45 angle divergent surfaces to which the vibrator itself, or an intermediary element, may be attached by means of complementarily shaped legs supplemented by clamping screws that draw the legs outwardly against the surfaces. In the use of a preferred embodiment, one of the sides of the mount is extended beyond at least one of the end walls to serve as a stop so that the mounting of the vibrator is limited in installation.

DESCRIPTION OF THE DRAWINGS FIG. I is a perspective of a vibrator mounted on an object to be vibrated;

FIG. 2 is a fragmentary elevation of the same;

FIG. 3 is a top view of the mount by itself;

FIG. Al is a section as seen along the line 4-4 of FIG. 3 but showing the intermediate element in position in broken lines;

FIG. 5 is an exploded perspective, on a reduced scale, of the elements making up the mount;

FIG. 6 is an enlarged fragmentary perspective illustrating one end and comer of the mount; and

FIG. 7 is a perspective, generally on the scale of FIG. 5, showing the use of an intermediary element.

DESCRIPTION OF A PREFERRED EMBODIMENT The numeral 116 represents a portion of the metal wall structure of an object to be vibrated, such as a concrete mold. Welded to this is a vibrator mount 12 on which a well-known form of rotary vibrator I4 is mounted by means of an intermediary or secondary element I6. In the present case, the vibrator has legs or cars 16 for receiving capscrews 20 which thread securely into tapped bores 22 in .the element I6. In

other instances, the vibrator may be provided with the element 116 as an integral part thereof, but the mounting to the mount I2 will follow the description below, since the element in different attitudes. The legs 2d converge at angles of I generally 45 to the bar 28, for purposes to be described below.

The mount I2 is of special construction, comprising a rigid steel boxlike structure having a pair of elongated parallel sidewalls 36 and 32 of equal height so that, with reference to a horizontal plane, their upper and lower edges are parallel to each other, but the sidewall 30 is trapezoidal and the sidewall 32 is rectangular so that in its lower end portions the length of the sidewall 32 exceeds that of the lower portions of the sidewall 36 in the triangular areas 341. See FIGS. 2, 4, S and 6. These areas provide stops to limit movement of the vibrator in one direction when the converging legs 24 of the secondary element 16 are mated with inclined end walls 36 of the mount I2. The end walls 36 are welded to the sidewalls 3t) and 32 at 36, duplicating or matching the angles, respectively, of the element legs 24. The mount I2 is itself welded at 40 to the wall II), it being understood that there is a like weld bead along the lower edge of the mount opposite from that visible in the drawings. This rigidities the mount with the wall III.

The mount is further supplemented at each end by a crossmen iber 42 in the form of a steel angle having the upper and lower free edges of its legs welded at M to the associated end wall 36. The members 42 not only contribute to the structural strength of the mount I2 in critical areas but also provide flat upper abutment surfaces against which clamping screws 66, threaded through tapped bores 4% in the element I6, seat when the element and vibrator are mounted on the mount I2 via the mating legs 24 and end walls 36 (FIG. 4).

In use and operation, the mount I2, or as many as may be desired, is, after prefabrication to rigidly unite the components 30, 32, 36 and I2, welded to the object, typically denoted here as the wall III of a concrete mold. The vibrator I4, previously attached to or formed with the secondary element 16, is slid sidewise onto the mount I2 and is stopped by the stops 36, which is especially helpful if the slide-on movement is vertical or nearly so. The clamp screws 46 are then tightened and the vibrator becomes in effect a unitary part of the object to be vibrated. Because of the 45 clamping angles among the legs 24 and end walls 36, remarkable holding power results, and the clamp screws need furnish only a portion, say a third, of the clamping force required. Where several mounts 12 are employed, the clamp screws may be easily manually loosened and the vibrator mounted elsewhere on the object.

As best shown in FIG. 2, the legs 2d terminate well above the wall Ill so that additional welding may be provided without interfering with the mounting and dismounting of the vibrator; i.e., such welds may be crosswise of the elongated weld beads 60.

Because the parts may be made from readily available steel stock, the mount and its associated parts may be easily and cheaply fabricated to provide a low-cost but extremely durable construction.
